Santa Catarina state is composed mainly of European descendants and the result is a lively composition of different cultures living within short distances. October is when festivals happen along different cities in the state, keeping the old traditions together and also inviting visitors to participate and learn more about it.
In each festival there are many music and dance events, traditional gastronomy, locals wearing folk dresses and so on.

The Oktoberfest Blumenau is the biggest and most popular one, considered the second to the original one in Germany. A good opportunity to drink lots of good beer - if you really like it - and also see the rich mixture that Brazil is made of and feel how happy they really are.

I could not end this post without mentioning the Rio de Janeiro win to host the 2016 olympic games. Like all Brazilians here and around the world I am very happy and proud. Times have changed and we are not a troubled nation anymore. Our president cried because it was great achievement, certainly an opportunity to call the worlds attention to this part of the Globe.
I have been to Rio and I saw that besides the urban problems, it is a top destination, with a unique beauty that can amaze anyone.
